Definitions
- This invention relates to Transcranial Magnetic Stimulation (TMS) in general, and more particularly to novel methods and apparatus for providing transcranial magnetic stimulation to an individual.
- TMS Transcranial Magnetic Stimulation
- the present invention provides a novel method and apparatus for providing Transcranial Magnetic Stimulation (TMS) to an individual.
- TMS Transcranial Magnetic Stimulation
- the present invention comprises the provision and use of novel TMS apparatus which allows the spatial, strength and temporal characteristics of the magnetic field generated by the TMS apparatus to be custom tailored for each individual, whereby to provide individual-specific TMS therapy and/or diagnostic testing. It also affords greater flexibility in open-ended investigations of brain function in neuroscience research.
- each of the magnet assemblies is configured to provide a rapidly changing magnetic field of at least 500-600 Tesla/second.
- each of the magnet assemblies is configured to provide a rapidly changing magnetic field of at least 500-600 Tesla/second.
- apparatus for creating a variable magnetic field in a region of space comprising:
- FIGS. 1 and 2 are schematic views illustrating novel apparatus for providing Transcranial Magnetic Stimulation (TMS) to an individual;
- TMS Transcranial Magnetic Stimulation
- FIG. 3 is a schematic view illustrating how selective ones of the magnet assemblies of the TMS apparatus of FIGS. 1 and 2 may be activated at selected times so as to provide the desired TMS therapy to an individual, diagnostic testing and/or investigative protocol in neuroscience research;
- FIG. 4 is a schematic view illustrating the physics of magnetic stimulation in a conductor
- FIG. 5 is a schematic view illustrating the biophysics of magnetic stimulation of a brain
- FIG. 6 is a table illustrating some of the advantages of the present invention over conventional TMS
- FIG. 12 is a schematic view illustrating still another form of magnet shield shutter mechanism.
- FIG. 13 is a schematic view illustrating novel apparatus for providing TMS to an individual, wherein the magnet assemblies further comprise a servomotor for changing the orientation of the rotating permanent magnet.
- head mount 10 comprises a soft, form-fitting skull cap adapted to cover the head of the individual while leaving the face and ears of the individual exposed.
- Head mount 10 is intended to provide a stable support for the aforementioned magnet assemblies 15 , and to that end head mount 10 preferably comprises a textile construct (e.g., woven, braided or knit fibers) that has a stable structure but which can breathe (for comfort of the individual).
- the head mount could be constructed of other materials such as soft plastic.
- Head mount 10 preferably includes a chin strap 30 so that the head mount can be fastened onto the head of an individual with light tension, whereby to ensure that the head mount maintains a fixed position on the head of the individual.
- TMS apparatus 5 also comprises a computerized controller 25 for independently controlling the operation of each of the magnet assemblies 15 , i.e., turning motors 45 on or off, regulating the speeds of motor rotation, etc.
- Leads 20 connect computerized controller 25 to each of the magnet assemblies 15 .
- TMS therapy and/or testing is to be applied to the individual, the individual puts on head mount 10 , the clinician or investigator mounts the appropriate number of magnet assemblies 15 to head mount 10 , positioning those magnet assemblies at the appropriate locations on head mount 10 , and then computerized controller 25 thereafter controls which magnet assemblies 15 have their magnets rotated when, and at what speed.
- computerized controller 25 thereafter controls which magnet assemblies 15 have their magnets rotated when, and at what speed.
- head mount 10 may include a plurality of electrodes 60 for monitoring changes in the electrical activity of the brain of the individual.
- magnet assemblies 15 may be constructed so that magnets 50 are moved longitudinally, rather than rotationally, by actuators (e.g., linear actuators) in order to produce a rapidly changing magnetic field. See, for example, FIG. 7 , where the actuators comprise solenoids 65 to move magnets 50 rapidly so as to create the changing magnetic field utilized in the present invention.
- actuators e.g., linear actuators
- the magnet assembly may comprise a moving permanent magnet to provide the desired changing magnetic field and the magnetic shield shutter mechanism may be omitted; in another form of the invention, the magnet assembly may comprise a stationary permanent magnet and the magnetic shield shutter mechanism may be used to provide the desired changing magnetic field; and in another form of the invention, the magnet assembly may comprise a moving permanent magnet to provide a changing magnetic field and the magnetic shield shutter mechanism may be used to modulate the changing magnetic field created by the moving magnet so as to provide a desired changing magnetic field at the anatomical location.
- magnet assembly 15 and its associated magnetic shield shutter mechanism 100 are preferably configured as a unit, with magnet assembly 15 and its associated magnetic shield shutter mechanism 100 being contained in a housing 122 , such that when that magnet assembly 15 is mounted to head mount 10 (e.g., by mounting housing 122 to head mount 10 ), its associated magnetic shield shutter mechanism is also mounted to head mount 10 .
